Abstract

PURPOSE:To advantageously obtain a double stick cosmetic without using a mold by forming a cylindrical outer ring cosmetic in the inner wall of a sleeve by vertically sliding an inner dish in the sleeve, packing inner ring cosmetic having different color tone in the hollow part and cooling and solidifying the cosmetic. CONSTITUTION:A cosmetic heated and melted from upper opening of a sleeve 1 is packed into space between the inside of the sleeve 1 and upper part of an inner dish 2 at the position raising the inner dish using a vessel for stick cosmetic having inner dish 2 capable of vertically sliding in the sleeve 1 and then the inner dish 2 is lowered and outer ring cosmetic part 41 is cylindrically formed in the inner wall of sleeve 1 and cooled and solidified. Then a cosmetic 5 differing in color tone from the above-mentioned cosmetic 4 is heated and melted and packed into the hollow of the outer ring cosmetic and cooled and solidified to form an inside cosmetic part 51 and double stick cosmetic such as lip stick is advantageously obtained in reduced number of process without using a mold unsuitable to automation or mass production.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a method for producing a double-stick cosmetic, and more particularly, to a lipstick, foundation, etc. that has a plurality of different tones in its outer periphery and inner part. The present invention relates to a method for producing a rod-shaped cosmetic.

(Prior Art) Various attempts have been made to obtain such double-stick cosmetics.
No. 21409, JP-A-54-113445,
JP-A-61-112008, JP-A-63-166818) and a method of spraying or flowing a slurry cosmetic onto a rod-shaped core material (JP-A-63-188615, JP-A-63-1811616). It has been reported.

(Problems to be Solved by the Invention) However, since all of these methods were only for molding the bar-shaped cosmetic itself, in actual production, the attachment to the dispenser container required additional steps. In addition to this, there is a problem in that this attachment is likely to damage or damage the bar-shaped cosmetic during the process, resulting in the production of defective products.

In addition, especially in the case of a method using a mold, there is a drawback that peeling failure is likely to occur when the molded cosmetic is removed from the mold, and the mold needs to be cleaned and treated with a release agent after each molding. In addition, because it is unavoidable to increase the size of peripheral equipment for heating and cooling the mold, it is not suitable for mass production through automation.

Therefore, the present inventor has conducted various studies to solve the conventional problems in such a situation, and as a result, the present inventor has developed a cosmetic dispensing container.
The present invention was completed by discovering a method for directly filling and molding bar-shaped cosmetics having multiple colors.

(Means for Solving the Problems) That is, the present invention uses a bar-shaped cosmetic container having an inner plate that slides up and down in a sleeve, and when the inner plate is in a raised position, the inside of the sleeve and After filling the space formed by the upper part of the inner plate with the heated and melted cosmetic from the upper opening of the sleeve, the inner plate is lowered to form a cylindrical outer cosmetic part on the inner wall of the sleeve, and then cooled and solidified. Thereafter, a heated and melted inner cosmetic material having a different color tone from the above is filled into the hollow of the outer cosmetic material portion, and is then cooled and solidified.

Hereinafter, the manufacturing method of the present invention will be explained in more detail using the drawings.

The cosmetic container used in the present invention is, for example, a dispensing container comprising an inner plate 2 that slides into a sleeve 1, as shown in FIG. The material of the sleeve 1 and the inner plate 2 may be metal, synthetic resin, etc., as long as it can withstand the heat of the molten cosmetic.
It does not matter whether the shape is cylindrical, elliptical, rectangular, etc. It is particularly preferable that the feeding mechanism be such that the inner plate 2 itself slides straight without rotating.

In the method of the present invention, first, the inner plate 2 is raised (see Fig. 1 (1)).
), the first step is to fill the heated and melted cosmetic material 4 from the nozzle 3.
(2), (3)) Then, when the inner plate 2 is immediately lowered, a cylindrical outer cosmetic part 4 is formed on the inner wall of the sleeve 1.
1 is formed (Fig. 1 (4), (5)). Then,
After cooling and solidifying this, the heated and melted cosmetic 5 having a different color tone from the cosmetic 4 is added to the outer cosmetic part 41.
If it is filled into the hollow and cooled and solidified, a double rod-shaped cosmetic can be obtained (Fig. 1 (6), (7)). By blowing hot air from the hot air nozzle 6 and/or blowing cold or hot air onto the side wall of the sleeve 1, the thickness of the outer cosmetic material can be easily controlled. That is, when forming a thick outer ring cosmetic material with a thickness of 31 to 4 mm, for example, cool air of about 10° C. is applied to the side wall of the sleeve 1 to cool it, and the inner plate 2 is lowered to a thickness of 0.2 m.
When forming a thin outer ring cosmetic material with a thickness of m to 0.5 ms, for example, cold air of 10 to 15° C. is applied to the side wall of the sleeve 1, and at the same time hot air of 80 to 85° C. is blown from the upper opening of the sleeve 1 through the nozzle 5. while lowering the inner plate 2 (Fig. 2).

(Effects of the Invention) According to the method of the present invention, cosmetics can be directly filled and molded into a cosmetic dispensing container without using a mold, so peripheral equipment for heating and cooling the mold becomes large. When removing the molded cosmetic from the mold, peeling failure occurs; when setting the molded cosmetic in a container, the cosmetic is easily damaged; and after each mold, the mold must be cleaned and a release material must be applied. It is possible to wipe out the shortcomings such as necessity.

Furthermore, the method of the present invention has a small number of steps and is suitable for automation and mass production.
